The invention discloses an in-situ reactive power compensation switching device and method, and relates to the technical field of reactive power of electric power. The device comprises a timer, an intermediate relay, a contactor and a capacitor which are electrically connected in sequence. According to the method, the intermediate relay is controlled through the timer, and then the contactor is controlled to open or close through the intermediate relay based on the timer, the intermediate relay, the contactor and the capacitor which are electrically connected in sequence; and effective compensation is achieved through the timer, the intermediate relay, the contactor, the capacitor and the like, the power factor is improved, and the loss is reduced. 本发明公开了就地无功补偿投切的装置及方法，涉及电力无功功率技术领域；装置包括依次电连接的时间定时器、中间继电器、接触器和电容器；方法为基于依次电连接的时间定时器、中间继电器、接触器和电容器，通过时间定时器控制中间继电器，再通过中间继电器控制接触器分或者合；其通过时间定时器、中间继电器、接触器和电容器等，实现了有效补偿，功率因数得到提升并降损。
